Amplifing variable 0-5 v dc voltage to 0-10 voltge range

AI Thread Summary
An engineering project focused on creating an automatic irrigation system is facing challenges with a humidity sensor that outputs 0-5 volts, while a PLC requires a higher voltage for optimal performance. The discussion seeks suggestions for a voltage amplifier or circuit design using an operational amplifier (op-amp). A non-inverting amplifier configuration is recommended, with a gain of 2V/V, achieved by setting R1 equal to R2. Participants are encouraged to share circuit designs or components that can effectively amplify the sensor's output to meet PLC requirements. The goal is to enhance the system's functionality through appropriate voltage amplification techniques.

i am middle of engg project . to make an automatic irrigation system ,using plc , main problem is humidity sensor which i am using gives out put of 0-5 volt but plc require more output for better results,...can anyone suggest a voltage amplifier or any circuit using op amp

Try to use op amp non inverting amplifier with gain equal to 2V/V (R1 = R2).
 

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Question about the voltage between two charged capacitors'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...

Thread 'Weird near-field phenomenon I get in my EM simulation'

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
